Finding Min/Max value in a Series

[RandyT]

Trying to figure out how to pass around arrays of double and find the min() or max() value in that Series.

Tried to just create a double array, but that seems to have initialization challenges.

Have resorted to doing this in a Series, but cannot find a method that allows me to retrieve the value from the Series.

Help appreciated.

Code is roughly:

dval1 = new Series<double>(this);

Looking to do something like:

dval1.Max()

Actually am working with NT8 and mistakenly started this in NT7 forum...

Hello RandyT,

Thanks for your post.

Arrays are a general C# concept, not to be confused with Series<T> objects, that you may find resources for externally to NinjaTrader.

Series<T> objects are publicly documented in the help guide with example code to demonstrate how they are created. I may also recommend referencing how the Strategy Builder generates the NinjaScript syntax. You may create a Series<double> in the Additional Data page under Custom Series.

Syntax from the help guide:

private Series<double> myDoubleSeries; // Define a Series<T> variable. In this instance we want it
                                      // as a double so we created a Series<double> variable.
 
// Create a Series object and assign it to the variable
protected override void OnStateChange() 
{
    if (State == State.DataLoaded)
    {
        // "this" refers to the NinjaScript object itself. This syncs the Series object to historical data bars
        // MaximumBarsLookBack determines how many values the Series<double> will have access to
        myDoubleSeries = new Series<double>(this, MaximumBarsLookBack.Infinite);
    }
}

The MIN and MAX indicators can then be used to look at the minimun and maximum values going a specified number of bars back. The Strategy Builder can also be used to generate this syntax.
